Dear Tom and Frank, thanks for the help on C. atlantis. Now, I request some help from the whole list. The list below has all the Cyphoma species I could narrow out. Now, I would like to know, are there any species on this list that are not true Cyphoma? Also, could anybody inform me of any true Cyphoma species are NOT on this list? I am trying to collect the whole genus. Cyphoma alleneae Cate, 1973 America Cyphoma emarginatum Sowerby, 1830 West Mexico Cyphoma gibbosa Linnaeus, 1758 Caribbean Cyphoma macgintyi Pilsbry, 1939 Florida Cyphoma macumba Petuch, 1979 Brazil Cyphoma rhomba Cate, 1978 Florida Cyphoma sedlaki Cate, 1976 Florida Cyphoma signatum Pilsbry & McGinty, 1939 Caribbean Thanks, James
